I had one when they were new. Drilled w/ pin by ring, CG under middle finger (ie, CG just on the negative side). Rolled as you might expect a CG neg. ball to roll; very smooth thru the mids, not jerky on the back, didn't cover a lot of boards but hit very well. I used this ball mostly when I needed to play deep. It was best on medium to med/dry (as was previously said), but could handle a bit of oil if it had to.
